Provided is a method and a device for transmitting an Ack/Nack of sPUCCH in response to the reception of short TTI-based sPDSCH in a 3GPP LTE/LTE-Advanced system. A base station may set, for each terminal, an offset value for setting a link between sPDSCH and sPUCCH, and transmit the set offset value to the terminal through upper layer signaling (RRC signaling), thereby enabling a terminal to use the offset value to allocate sPUCCH resources for transmitting an Ack/Nack in response to the reception of sPDSCH.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of transmitting a short uplink physical control channel (sPUCCH), the method comprising: receiving a downlink data channel from a base station; receiving an user equipment (UE)-specific offset value to transmit the sPUCCH for the downlink data channel through higher layer signaling; and transmitting the sPUCCH including ACK/NACK information for the downlink data channel through a resource determined based on the UE-specific offset value, wherein a 2-bit value of a sPUCCH field is included in a downlink control information (DCI) for determining the resource to transmit the sPUCCH for the downlink data channel.
2. The method according to claim 1 , wherein the higher layer signaling comprises a radio resource control message.
3. The method according to claim 1 , wherein a time interval for transmitting the downlink data channel is different from a time interval for transmitting the uplink control channel.
4. A method of receiving a short uplink physical control channel (sPUCCH), the method comprising: transmitting a downlink data channel to a user equipment; transmitting an user equipment (UE)-specific offset value to receive the sPUCCH for the downlink data channel through higher layer signaling; and receiving the sPUCCH including ACK/NACK information for the downlink data channel through a resource determined based on the UE-specific offset value, wherein a 2-bit value of a sPUCCH field is included in a downlink control information (DCI) for determining the resource to receive the sPUCCH for the downlink data channel.
5. The method according to claim 4 , wherein the higher layer signaling comprises a radio resource control message.
6. The method according to claim 4 , wherein a time interval for transmitting the downlink data channel is different from a time interval for transmitting the uplink control channel.
7. A user equipment for transmitting a short uplink physical control channel (sPUCCH), the user equipment comprising: a receiver configured to receive a downlink data channel from a base station and receive an user equipment (UE)-specific offset value to transmit the uplink control channel for the downlink data channel through higher layer signaling; and a controller configured to determine a resource for transmitting the sPUCCH based on the offset value and transmit the sPUCCH, wherein a 2-bit value of a sPUCCH field is included in a downlink control information (DCI) for determining the resource to transmit the sPUCCH for the downlink data channel.
8. The user equipment according to claim 7 , wherein the higher layer signaling comprises a radio resource control message.
9. The user equipment according to claim 7 , wherein the a time interval for transmitting the downlink data channel is different from a time interval for transmitting the uplink control channel.
